Large $Y_{k, b}$ -tilings and Hamilton $ℓ$ -cycles in $k$ -uniform hypergraphs

Luyining Gan, Jie Han, Lin Sun +1

Let $Y_{3, 2}$ be the $3$ -uniform hypergraph with two edges intersecting in two vertices. Our main result is that any $n$ -vertex 3-uniform hypergraph with at least $\binom{n}{3} - \…

A note on algebraic connectivity of 2-connected graphs

Guanglong Yu, by Shuguang Guo, Lin Sun +2

Among all simple 2-connected graphs, and among all $θ$ -graphs, the graphs with the minimum algebraic connectivity are completely determined, respectively.

Guanglong Yu, by Lin Sun, Chao Yan +2

Among all simple nonbipartite 2-connected graphs and among all nonbipartite $θ$ -graphs, the minimum least $Q$ -eigenvalues are completely determined, respectively.
